Abstract

Devices and methods of use for introduction and implantation of an electrode as part of a minimally invasive technique. An implantable baroreflex activation system includes a control system having an implantable housing, an electrical lead, attachable to the control system, and an electrode structure. The electrode structure is near one end of the electrical lead, and includes a monopolar electrode, a backing material having an effective surface area larger than the electrode, and a releasable pivotable interface to mate with an implant tool. The electrode is configured for implantation on an outer surface of a blood vessel and the control system is programmed to deliver a baroreflex therapy via the monopolar electrode to a baroreceptor within a wall of the blood vessel.
